Tremco Vulkem® 45 SSL Polyurethane
is a one-part moisture curing, low modulus polyurethane sealant especially
developed for sealing joints in level and/or slightly sloped surfaces.
Exceptional wear and tear resistance in high traffic areas. High adhesive
strength to common construction materials make Tremco Vulkem 45 SSL
the choice for a wide variety of requirements. Use
Vulkem 45 SSL in
expansion joints in sidewalks, parking decks, plazas, floors and other
horizontal surfaces with slopes of up to six percent. Light tooling can be done
immediately after application if necessary. Suitable for use in continuous water
immersion.

Important Note:Do not apply over damp or contaminated surfaces; not
recommended for areas subject to high pedestrian traffic unless covered with
metal traffic plate.
Check cartridge label and Specification Data Sheet for additional limitations

Joint design: Vulkem 45 SSL may be used in any
horizontal joint designed in accordance with accepted architectural/engineering
practices. Joint width should be 4 times anticipated movement, but not less than
1/4” (6.4mm).

Joint backing:
Closed cell backer
rod or reticulated polyethylene backer rod is recommended as joint backing
to control sealant depth and to ensure intimate contact of sealant with joint
walls. Backer rod needs to be properly friction fitted for use with
self-leveling sealants to prevent leak out of sealant during cure. Where depth
of joint will prevent the use of backer rod, an adhesive backed polyethylene
tape (bond breaker tape) should be used to prevent three-sided adhesion. All
backing should be dry at time of sealant application.
